TOP-LIFTV-TRIMMING MACHINE.

Application led August 25, 1927, Serial No. 215,478, and in Great Britain September 30, 1926.

This invention relates to trimming machines and is herein illustrated as embodied in a. machine designed With regard' particularly to trimming vthe top lifts of heels that have been previously developed to final shape. In the manufacture of womens shoes provided with wood heels, for example, it is the practice to shape the heels and cover them before attaching the top lifts'. Then, after attaching the ytop lifts, which` are initially oversizaitis necessary to trim them to conform them to the heels with regard not only to their contours but also with regard to their profiles. One ofthe problems always present in such trimmingv is to trim the top liftiiush with the cover of the heel Without mari-ing the cover. Stated generally, an object of the invention is to provide an imi'irovcd machine for doing this kind of trimming.

Good ishoemaking practice also, requires slightly beveling of the edge of the toplift at the tread surfaceto remove the sharpedge Vandto improve the appearance of the heel,

and although top lifts are graded accordingy to their thickness those attached to one lotv of heels, While of uniform thickness, are usually thinner or thicker than those attached to another lot of heels. Thus, when, as formerly. a single 4cutter is used to do both the trimming and the lieveling simultaneously. s uch a cutter suitable only for a certain thickness of top lift, and it 1t 'is used on` thinner top lifts and set to produce the necesof various thicknesses. to the end that uni- Y formity of the bevel and flush trii'nming may both be accomplished `Without marringthe vcovers of the heels. 5

To accomplish the above-mentioned'objects a feature of the invention consists in a novel 'combination comprising a rotary edge-trimganized to provide two relatively adjustable groups or units of which one includes the contour cutter, While the other includes the tread-rest and the lieveling cutter. These two groups or units, moreover, are so related that the meeting fa-'ces of the heei and top lift may be located in the plane of one end of the contour cutter by Contact of the tread face of the top lift with the tread-rest. Thus, by relatively adjusting the two said groups in accordance with the thickness ofthe top lifts, the contour cutter may be prevented from lapping and possibly scraping or cuttingr the heel cover, but since adjustment of the kind referred to does not change the relation between the beveling cutter and the tread-rest, uniform bevelimer is assured irrespective of adjustments made because of the thickness of the top lifts.V y

While trimmingr the sidesl and back of a top lift, it is desirable to utilize a heel-support, not only to relieve the operator from the necessity for sustaining the heel against the stress applied by the cutters, but also to maintain the top lift in a substantially uniform relation to the cutters, since this operation requires turning' the heel whileV the cutters are operating'. On the other hand, When trin'nning the breast of the top lift, it is not `feasible to use a heel-support since this operation requires moving the heel bodily past the cutter rather than turning); Vit rotatively. To u'ieet these conditions the illustrated machine comprises a heel-support adapted to be shifted quickly to and from an operative position so that with one handling of a heel said support may be utilized While trimming around the sides and back of the top lift but may be removed from its operative position to avoid obstructing?,r the work While the breast of the top lift is being' trimmed.

In-many heels of the type above referred to, for example Louis heels. the pitch or slant the plane of the tread surface, While around the sides and back it may have a considerable pitch or slant due to the flaring formation of the heel body adjacent to the top lift. Gonsequently@ the'operation of trimming the top i litt to conform to the heel body vvvherethe tivo elements meet involves not only the matter contour, but `also the problem of conformingjthe profile-of the top lift to that of the heel body, to the end that the breast as Well as the sides and back of the top lift will merge smoothly into the heel body'- and forinpin effect, a continuation of the latter without any*perceptiblefbreaky or 'change fof pitc'hat the meeting;r plane.

Accordiiglyi"with regard to thelatter considei'ation, fan object' of 'the-invention is kto provide for utilizing' themfnfei'nfents'l of the heelesupport to' andy from itoperat-iv'e position'to deflect the" desired' change of pitch 'of tthe profileofthe trimmed/:top lift". l f

To this end a feature ofthe invention consists inl means arranged to communicateshiftine movement of 1th`e` heel-supportto"the 'tread-rest insuch away as to'sli'ift th'elatter bacli and forth'fromonetotheothei oftlvo operative positions' angularly relatedtofeach other. s `Theillustratedmeans forthis purpose i designed `to `vt'io'rdinate'the` n'iovements "of the tread-rest and the heel-support`-so Athat Awhen' the latter is in its operative positron the angle o f the tread-rest vvill be suitable 'f'orxtriminingl thei back and sidesiof thetop lift l and when `the heel-support is' displaced fromits operative position'jas described7 the angle :of the tread-rest Willbel suitable 'for trimn'iingl the breast of the top lift.

"exactly at right angles to the plane of the tread face 56 of the toplift, is nevertheless more nearly at right angles thereto than is the profile around the sides and back adjacent to the toplift. Therefore, to continue the profile of the yheel body into the topliftV it is necessary to maintain the tread face 56 in one planewhile trimming around the back and sides, and in anotherplane angularly related to the first said plane while trimming the breast. The angular relation of these two planes for aheel of the style` shown is indicated in Fig. 5 by broken lines a and b. It

`willbe observed that the relation between the line b and the profile ofthe cutter 20 is more nearly right-angular, whereas the relaj through which a vertical pivot pin 64 extends to connect the tread rest with an adjustable support 66. This support is formed with a cylindric shank or stem 68 arranged to slide horizontally in a bearing 70 formed in the frame 10. A key 72 (Figs. 1 and 4) and groove 74 form a spline connection to prevent turning movement 0f the stemabout its axis.

The bearing 70 is preferably split at its under side and is provided with abolt 7 6 by which it may be contracted to clamp the stem 68. For the purpose of adjusting the tread rest along lines parallel to the axis of the cutters and in `accordance with the thickness of the i ll() i Tlie pivot pin 64, in addition to connecting the tread-rest and the support 66, extends also through the bell crank lever 40 which is carried by said support. Furthermore, the

adjusting screw 44, by which' the beveling cutter 26 is adjustedrelatively-to the cutter- 20, is carried Aby the support 66. yConsequently, when the support 66 is adjusted by lmanipulation of the handle 84 to shift the tread-rest forward or back, the beveling cut- Vter 26 partakes of this adjustment and remains in constant relation to the tread-rest.

The aforesaid angular adjustmentof the tread-rest consists in movement about the axis of the pivotpin 64 and is effectedby an arm 86 formed with a cam surface`88 (Fig. 3). The arm 86 is affixed to a rock-shaft 90 journaled in a boss 92 formed on the treadrest (Fig. 2), and for this purpose the arm is preferably split, as shown in Figs. 1

and 4, and is provided with aibolt 94 by which it may be contracted to grip the rock-shaft tightly. The cam surface 88 is formed at the left-hand end ofthe arm 86 as viewed in Figs.

1 and 2 and cooperates with an adjustable abutment 96. A tension spring 98 is yconnectedat its forward end to the tread-rest, and at its rear end to the frame 10, its effect being to draw the tread-rest toward the rear and thereby maintain the arm A86 against the abutment 96. The abutment'96 is shown as a screw and is carried by the adjustable support 66. Consequently, since the abutment 96 partakes of adjustments of the support 66, these adjustments do not affect the angular adjustment of the tread-rest. The screw 96 serves to maintain the work-engaging face of the tread-rest in the angular position indicated by broken line a in Fig. 5, although this angular position is, of course, subject to variation by adjustment of said screw. lVhen the arm 86 :is in the position shown, its left-hand end is supported by a lug 100 (Fig.

3) formed on the tread-rest.

lWhen it is desired. to shift the tread-rest from the position indicated by broken line a (Fig. 5) to that represented fby broken lineA 7), the rock-shaft 90 is turned in a clockwise direction to disengage thearm 86 from the abutment 96. This disengagement enables the spring 98 to draw the tread-rest to the rear by swinging it slightly about the axis of the pivot pin 64. The extent of angular movement of the tread-rest is controlled by a second abutment shown as a screw 102. This `screw is also carried by the support 66 and is arranged to engage a portion `104 l) of the arm 86, whichportion is preferably semicircular to maintain its abutting contact with the screw 102 when the arln 86 is turned clockwise approximately o from the position shown. This turning movement of the arm 86 is arrested by a lug 106 projecting from the tread-rest and arranged to be engaged by a pin 108 carried by the arm. )Vith this construction the tread-rest may be shifted back and forth from one to the other of its two'angularly related operative positions each ofwhich is variable.independently of the other. j j j The machine is also preferably provided with a heel support to sustain the heel against the cutting stresses. In the illustrated machine the support for this purpose comprises an arm 112 and a heel-engaging roll 110 carried thereby. This support is useful in trim- .ming aroundthe sides-and back of a toplift,

since such trimming is executed progreslll.'

` vAssuniinp;that the machine is about to be use dfto trim the toplift of a heel, and that :all the'nece'ssary adjustments have been made,

the operator may begin by first trimming' the 'toplift flush with thesiiles and back of the heel body. For this part of the operation the supporting` roll 110 and the trii'nminf:Y page 120 will occupy thepositions shown in Fig.

1.v The machine is capable of' y'operating either on an i'inattached heel or on a heel has been attached to a shoe as represented'in. Fig. 5,' As the,h'ee'li s 'rotated in contact with the supporting roll 11O7and the edge 122 of the'trimming gage, the operatorl will main-` tain the tread face 56 of the topliift in Contact with the tread-restGO to control the pitch of j i the prolile generated by the trimming cutter 20.' Alt tliistii'ne the Work-eng'agingsurface` of the tread-rest 60 Will standin the position indicated by broken line L in Fig. the vcutter 20 is operatingr to trim' the back and sides ont-'thel toplift flush Withthe body 'ot' the heel, theV supplemental cutter 26 operates to bevel Vthe tread surfaceas indicated Vat IIaving'trimmed around the sides and back'oi" ythe toplift, the' operator will proceed to" trim the breast, but before doing so he will iso swing the supporting roll 110 upwardly and to the right to remove it from the field of operation so that the heel may be moved bodily up or down without encountering said roll. The act of swinging the supporting roll 110 away from its operative position results in changing the angle of the tread-rest from` the position indicated by the broken line a to that indicated by the broken line b in Fig. 5,

the latter position being the one better suited to the ie uiiements of breast-trimming. If,

now, the reast of -the h eel is concave, as rep- 'or down in contact with the right-hand edge of the gage, the cutters20 and 26 now being effective to trim and bevel the breast of the toplift. i

Since the tread-rest 60 and the supporting roll 11() are in their respective breast-triinming positions inconsequence of tlieprocedure above described, the order of pro-` cedure for the next heel may be the reverse .of that described, to avoid making unnecessary changes in their positions.

Thus, the trimming ofthe next toplift will preferably be begun by firsttrimming and lieveling the breast, and when this step'has been accomplished the supporting roll 110 may be .returned to the position shown. By returning the su porting roll 110 to its operative position, t e arm 8 6 will be caused to re-engage the screw 96, andthe cam, surface 88 will cooperate with said screw to shift the tread-rest from the position indicated by bioken line b and back of the topliftfV Although the support is adjustable to i locate the edfres of the meeting faces of the previously made.l

heel body andthe toplift in the plane of the frontface of the cutter, adjustments for this purpose do not affect the angular adjustments of the tread-rest or the depth of the bevelingcnt, since the adjusting screws 96 and 102 as well as the bell-crank lever 40 and its adjusting screw 44 are all carried by said support. l Consequently, when the support 66 is adjusted with regard to the thickness of a lotof toplifts, or even a single toplift, the screws 96 and 102an'd the beveling cutter will partake of suchadjustment and maintain their respective individual adjustments Having described our invention, what we claim as new and desire tosecure by Letters Patent of the United States is:-
